Sodium Laurel Sulfate

Dr. Ellie,

I love all the info on your site and I’m starting your program today I know you recommend Crest toothpaste, but I’m trying to eliminate sodium laurel sulfate from my personal care products I can’t find any info on its benefits but there are suggestions of problems. Have you tried Squigle toothpaste? It has fluoride and xylitol and no SLS. 


Dear CD,

I understand your concern about sodium laurel sulphate and I know that there is some in the Crest paste.

Interestingly, I have a number of patients who normally have an allergic reaction to this product but they are OK with the Original Crest Toothpaste. They cannot use other shampoos or personal care products that contain it but this one paste is OK for them. I have no idea why this would be the case but it is interesting that the Original Crest is OK but the other commercial pastes are not.

If you wanted to skip using toothpaste all together the system will still work for you.
Sometimes people use a drop of ACT on the toothbrush and it is an option. A tiny amount of Crest is another compromise.

The problem with many “health” toothpastes is that they are too abrasive. I have tried a number of pastes that contain wonderful myrrh, xylitol or fruit and iris extracts all great ingredients. The problem is that they appear to be made with pumice which works like abrasive sandpaper on your teeth (not good).

Toothpaste is measured on a scale of between 1 and 200 for how abrasive and scratchy it is. The ideal is to be around 100 when grading this abrasiveness. Crest comes in at 105 (FYI: Aim is 185 🙁 and Close up is 218 !!) Beware of any paste that removes tartar or for tartar control most are very abrasive (above 130 on this chart) and also very acidic.

Hope this helps!
